Which arch/arm/mach-* platform are you using for Juno?
I don't even know! :) I just start with a multi_v7_defconfig plus a few
extra bits (LPAE, KVM, sil24, sky2, etc.) and it works. I guess it's the

The ARMv8 architecture supports:
1. 64-bit execution state, AArch64.
2. 32-bit execution state, AArch32, that is compatible with previous
versions of the ARM architecture.
LayerScape platforms are compliant with ARMv8 architecture. This patch
is to support running 32-bit Linux kernel for LayerScap
